Gold

Gold is a metal that is soft and easily forged, hardness ranged between 2.5 - 3 (Mohs scale), and severe type depending on the type and content of other metals mixed with it.

Mineral gold carrier usually associated with follow-up minerals (gangue minerals). Mineral follow-up generally quartz, carbonate, tourmaline, flourpar, and a small number of non-metallic minerals.

Mineral gold carriers are also associated with sulphide deposits that have been oxidized. Mineral carriers consist of gold gold nativ, elektrum, telurida gold, some gold alloys and compounds with the elements sulfur, antimony, and selenium. Elektrum actually another type of nativ gold, only silver content in it> 20%.


Gold is formed from the process magmatisme or pengkonsentrasian on the surface. Some of the sediment formed by the process of contact and metasomatisme hydrothermal solution, whereas the mechanically produced pengkonsentrasian sediment Lay (placer).
